IMPROVEMENT IN CISTERN CUTv-OFFS.

vThe Schedule referred to in these Letters Patent and making'part of the same.

To all whom it may lconcern Be it known that I, J. P. WATSON, of Rochester, in the county ot Olmsted, andV State of Minnesota, have 'inventedcertain new and useful Improvements in Gut-Off ior Oistern-Feeders and other water conductors; and I do hereby-declare that the following is a i'ull, clear, and exact description thereof, reference beinghad to the accompanying drawings making part of this specification, and to the letters of reference marked thereon,like letters indicating like parts wherever they occur. i

'lo enable others skilled inthe'art toconstrucLand use my invention, I will proceed to describe it.

My `invention relates to a cut-oli' for eistern-feeders and other water conductors; and

It consists in a novel manner of constructing the same, and in providing it with a handle, whereby it can he operatedfrom within the building.

The drawing represents a vertical sect-ion through the center of my device.

` A is the water-conductor, having avrectangular en- Y largement or chamber, B, the front side, C, of which is hinged atits lower edge, so that it may he turned inward, as shown. f

To the front or outside of the hinged side or door D, I secure a chute or spout, D,"having 'a downward inclination, as shown, and across the back wall of the chamber B, l secure a ledge, e.

When thehinged side is turned inward, lit strikes against the hack wall of the chamber below the ledge e, and thus forms a. tight partition, which cuts oif the -ow of water down the pipe A,and causes it to pass through chute D,-which discharges it outside.

outside.

The rod E may be curved so as to cause its end to conform to thev movement of the ear a, or it may be passed straight through the wall and its outer end made elastic, so as to bend, or a slotted arm may be substituted for the ear a, and the end of the rod al lowed to play in the slot.

When the door is turnedup in its normal position, it closes the side of the chamber and allows the free passage of the water down the pipe. n

My device, thus constructed, presents a simple and ecient cut-off for theV purpose of regulating thesupply or feed of cisterns that can be operated from indoors, thus obviating the necessity of the operator exposing himselt'- during inclement weather.

Having tllns described my invention, f

1.- A water-conductor, having a chamber, B, with one of its sides, C, hinged'and provided with a spout, D', all constructed and arranged as herein described, and for the purpose set forth.

` 2. The combination of hinged side C, spout cross-bar provided with ear u, and curved rod E, when constructed and arranged as described.
